James May is mostly known as the sensible one from the U.K. show Top Gear. But he's also a bona fide tech nerd, and he's here to explain exactly how the digital camera in your laptop, smartphone, or dedicated point-and-shoot works.

Sat on top of a mountain in Chile is the world's most powerful digital camera. Known as the Dark Energy Camera, it's recently been fired up to image the night sky, in an attempt to find the exotic stuff that gets all physicists excited. These are the first images it's produced. And they're magnificent.

F-stop is to photography beginners what inorganic chemistry is to an MFA graduate: some kind of black magic that only makes sense to experts. That said, I'm sure plenty of seasoned photographers use f-stop numbers without knowing what they really mean, too. But no more, because this video explains the concept in a…

That's the smallest and lightest with an APS-C sized sensor, anyway. Adding on to the wildly-popular NEX range of ultra-portables, the NEX-C3 has a 16.2MP sensor, and weighs just 225g—that's 6 per cent less than the previous NEX model.

Were it an animal, the Casio TRYX would be enough to singlehandedly refute intelligent design. It's pretty. It's fun! It works well. But there's really no way to explain the strange, strange way it is.

Steven Sasson is a pretty unassuming guy. But he changed the world. In this "video portrait" by David Friedman, Sasson briefly walks us through the birth of the digital camera, and muses about its implications since then.

I don't remember very much from the mid-90s, but I'm certain I never saw Leica's incredibly strange (and damn beautiful) digital camera. It had awesome giant handles, and it took gorgeous photos. 20 yearsago. But the wait? Not gorgeous.

During the frigid Rochester winter of 1975, researchers at Kodak pieced together the future a quarter of a century early. Built from scavenged parts, the team had created their first "film-less" camera—an idea far ahead of its time.

Sanyo, long-time expert in making small but powerful dual cameras (video + still), just made its first Flip-type camera. Yes! It not only has Sanyo's expertise, it also has a 3X optical zoom and dual-mics that look like shoulder pads.

An impending update to the mini-projector sporting S1000pj we adored is on its way, according to leaked images by German mag Foto Digital. The S1100pj will add a touch screen and remote control, as well as other unrevealed improvements.

The BookLiberator Project is kit of open source hardware and software, designed to help you digitize your personal library without damaging your collection. It won't spare you from having to turn each page, but it is some seriously clever design.

A nice digital camera's an expensive investment, which is why it's so frustrating that the lens and LCD screen are often left so exposed. This concept—that flips a camera lid 360 degrees—would protect my soul-stealer but nice.

It's not a micro four thirds, but Pentax has lifted the lid on the 645D medium format camera, which will be available this May for close to $10,000. Why so expensive, you ask? There's that 40MP Kodak sensor for starters.

If you haven't got nearly enough of the cameras coming out of the PMA show this week, you couldn't go wrong with the 26x optical zoomer X90 from Pentax, which takes last year's X70 and ups the zoom-factor.

Announced at CES, the GPS-enabled EX-10HG from Casio has been a bit of a mystery so far, but has just been given full launch details, with the price expected to be in the region of $400 when it hits in October.

I'd be more excited if this special limited edition color was a never-seen-before color, but alas Pentax thinks the camera world can still get excited about silver. Or maybe silver is rare in Japan, where this model is launching?

Sony's announced a glut of new cameras today at CES, but instead of going through all 20-odd of them, I'm only going to show you the best. You deserve the best. Here's two of them, the DSC-W370 and DSC-W350.
